' UNITED STATES PATENT oF'F'lcE 2,528,572 AWNING WINDOW OPERATING DEVTGE' Joseph Bancroft, Jamestown, Applicatiori'June 17, 194s,seriarNki,-3;sf v

This invention relates to 'window sashes of the so-called awning type, wherein the sash is pivoted-in the window frame on horizontally-disposed-pivots at the sides of the sash near the upper edge of the-sasn-and the present improvements have reference to sash-operating means by which such :a sash, or'a plurality of sashes mounted one above the other and coupled together, can be smoothly, easily and conveniently moved to open, closed or intermediate positions. I

In most of the devices proposed for use in connection with 'awning sashes of this character, gearing, links, levers and arms andpther compleX devices are'em-ployed to such an extent as to make the cost of "manufacture, installation and maintenance very considerable, not to mention the fact that such devices possess the likelihood of failure of satisfactory operation, particularly after .some use,

The present invention, therefore, contemplates the provision of a greatly simplified and inexpensive sash-operating device having a, minimum of parts, and those employed being of sturdy construction so that an assurance of long life, smooth operation and general satisfaction is had.

More particularly, the invention contemplates the provision of a crank-operated plate or disk contained in a suitable housing secured to the. window frame in a convenient position for opera- 7 tion withinthe 'room', said plate -or disk being pivotally attached toone end of a link which has its-other end connectedbyaball-and-socket connection to asli'de mounted for 'slidable movement back and forth in a suitable guide channel provided-on the lower edge of the sash. The sash so connected to the operating means as above described may, if desired, be coupled by suitable connecting links to a plurality of other sashes arranged above it so that the several sashes will be simultaneously opened or closed by manipulation of said operating means.

These and other objects are attained by the invention, a more particular description of which will hereinafter appear and be set forth in the claims appended hereto.

In the accompanying drawings, wherein an illustrative embodiment of the invention is disclosed:

Fig. 1 is a vertical sectional view through a sash and frame therefor, showing the improved operating device;

Fig. 2 is a top plan view of the outer end of the sash-operating link or arm;

Fig. 3 is a vertical sectional view through said ZCIaims; (circa-aloe) *2 end'of the arm-or linkand the guide inwhich it is slidabile;

Fig. 4 is a view of the under sideof the'structure shown i-n Fig. 3;

Fig. 5 is a'top plan-view of the operating device, with parts broken away, and other parts in section,"to-discloseconstruction;

Fig. 6 is 'a top planviewof the rotative actuating member or plate, show-ing the pivotal attachment of one end of the operating link thereto, and

Fig. 7 isan edge view of said operating mem-' ber, looking at the right edge of Fig. 6.

The sash of' thecharacter to which the present invention is applicableis provided with-a frame I which-maybeof'me'tal or'wood construction, andit-includes'spacedvertical side bars 2,0ne of which is-shown in Fig. 1 connected in-the known manner at the topandhottom byhorizontal bars, the bottom oneof which is shownat 3. t fl is shown one of the sashes -pivotally mounted in the frame, 'sai d sash being-of rectangular form and having the side bars 5, upper cross bar 6 and lower cross barB. The conventional glass pane is omitted from the frame to simplify illustration. At theopposite ends of the upper cross bars are the pivots "for-the sash and which pivotally mountdt in the frame, 'said-pivots-being disposed horizontally, permitting the sash to swing'outwardly to open position, substantially asshown in Fig. 1. By means of theoperating device to be described, the sash can be opened or closed or moved to and "maintained in any desired intermediate position.

The sash'shown at "-4-is the lowermost sash in theframe I, and a'plurality of additional sashes pivotally mounted 'as "described, are usually arranged-in tandem orione above-the other within the frame ,I. The several sashes so mounted-are coupled togetherso that when the lowermost sash is moved by theoperating device,-the other sashes are simultaneously moved to a similar position. The several sashes are coupled together at their ends by links, a portion of one of said links being shown at 2!! in Fig. 1, said links being pivotally attached as at 2! to lugs 22 projecting from the several sashes. This coupled arrangement of the sashes is known in this art, and sashes arranged in the manner thus far described, are known as awning windows.

The improved operating device includes an arcuate housing I!) provided at its opposite ends with ears 25 through which screws I! extend to fasten the housing It to the vertical flange [2 of the bottom bar 3 of the window frame. Ro-

tatively mounted on a vertical pivot 26 and within the housing is a disk-like plate l4 provided with an arcuate slot 28, having a toothed'edge 29 constituting a rack for engagement by a pinion not shown, but located within the housing and mounted on the end of the crank 13. This structure is known in window-operating devices.

At [6 is shown an arm or link which is pivotally connected at I5 to the plate [4, said pivot l5 being a horizontal pivot allowing the arm or link [6 to swing up and down to an extent required by movement of the sash 4, as will be hereinafter explained. At its outer end, the arm 1 or link I8 is slightly offset and is provided with a ball or sphere I! that is received in a socket I9 provided on a plate l8 constituting a slide. Said slide I8 is slidably mounted in a channelshaped guide member 9 secured to and extending along the lower edge of the bottom cross bar.

8 of the sash frame 4. This arrangement is such that the outer end of the arm or link It; is slidably coupled to the lower edge of the sash- 4 and by means of the ball-and-socket coupling between the end of said arm or link l6 andrthe slide I8, a universal pivotal connection is established between the link I6 and the bottom of the sash. It will be noted that the housing It] is open at its forward end, as indicated at 32, and the flange I2 is cut-away or slotted as at 33, to permit rotative movement of the plate l4.

From the foregoing, the operation of the improved sash-operating device will be readily understood. By rotation of the crank [3, the plate l4 will be rotated about its vertical pivot 26 to swing the arm or link I6 in the required direction to cause the sash 4 and other sashes coupled thereto to be moved inwardly toward closed position or opened according to the direction of rotative movement of the crank I3. When the arm or link [6 is swung, its outer end will slide back or forth along the bottom of sash 4 required, by means of the slidable connection established between the plate IQ and the guide strip 9. Since the pivoted sash i travels in an arc it is apparent that the link must be capable of swinging upwardly or downwardly according to the direction of swing of the sash. The hinge l5 permits this up and down swing of the link l6 and the balland-socket connection between the outer end of the link 15 and the slide 18 allows this end of the link to position itself as required during the swinging movements of the sash.

When the sash is in its closed position, the arm or link It is disposed between the lower bar 8 of the sash and the top of the bottom bar 3 of the While I have shown one embodiment of the invention, it is obvious that the same is not to be restricted thereto but is broad enough to cover all structures coming within the scope of the annexed claims.
